It was reactivated as a normal fault in the Carboniferous with a downthrow to the northwest and again reactivated as a reverse fault during Late Carboniferous inversion associated with the Variscan Orogeny.
The exhibits depict the natural diversity of Alabama from the Age of Dinosaurs, the Coal Age, and the Ice Age.
Any Caledonian deformation is unclear but the fault zone was reactivated in the Carboniferous as a NW-throwing normal fault with seismic reflection data showing the formation of a half-graben in its hanging wall.
All occur where the river cuts a gorge through the Carboniferous limestone between the hills of Kisdon and Rogan's Seat.
In 1901 the coal pits at Doura were a good source of Carboniferous fossils.
(1913–1992) was an American invertebrate paleontologist. He was an expert on Carboniferous fossils.
Its coal seams were laid down in the Carboniferous period and some easily accessible seams were worked on a small scale from the Middle Ages and extensively from the beginning of the Industrial Revolution in the early 19th century until the middle of the 20th century.
Pangea was a conglomeration of all the global continental land masses, which lasted from the late Carboniferous through the mid Jurassic.
The Pennine Basin is a sedimentary basin which was active during the Carboniferous Period and which reached from the Southern Uplands of Scotland in the north to the former Wales-London-Brabant Massif in the English Midlands to the south.
The Alleghenian orogeny in North America (during the Carboniferous period) for example can be found as an angular unconformity between rock layers in large parts of that continent.
The Widmerpool Gulf is a name given to a sedimentary basin that existed as an area of open water during the Early Carboniferous (Tournaisian Age).
In the Yorkshire dales the Carboniferous rocks assume an aspect very different from that which obtains in the South.

The Yoredale Series, in geology, is a local phase of the lower Carboniferous rocks of the north of England.
Iranian geologist Manuel Berberian's research indicates that the Ipak Fault is at least as old as the Carboniferous period, and has probably been reactivated several times since its formation.
Within Pembrokeshire the Carboniferous Limestone forms the spectacular coastal cliffs at St Govan’s Head along from which are features such as Huntsman’s Leap and the Green Bridge of Wales, a natural arch.
On the beach beside the harbour, there are fossilised trees related to Horsetails, dating back to the Carboniferous geological period.
As well as major contributions to stratigraphy and geological mapping, G. N. Frederiks is particularly remembered for his contributions to the paleontology of the late Paleozoic era (Carboniferous and Permian periods), notably Brachiopoda, Ammonoidea, and Bryozoa.
Haptopoda is an extinct arachnid order known exclusively from only eight specimens from the Upper Carboniferous of Coseley, Staffordshire, United Kingdom.
His findings were published in his 1833 book The Internal Structure of Fossil Vegetables found in the Carboniferous and Oolitic deposits of Great Britain, illustrated by William MacGillivray.
Iniopterygiformes ("Nape Wing Forms") is an extinct order of chimaera-like cartilaginous fish that lived from the Devonian to Carboniferous periods (345–280 million years ago).
Before graduating from Yale’s Sheffield Scientific School in 1884, he showed a small collection he had made of Carboniferous fossils to George Jarvis Brush, who later introduced him to the paleontologist Othniel C. Marsh.
In addition to numerous miniature animal models and 2-D 'profiles', Zeman also used larger models of heads and bodies of animals (including a full-size 'dead' Stegosaurus and swimming woolly rhino, Brontosaurus and Trachodon models), as well as life-sized model plants (as in the Carboniferous forest sequence, and the encounter with the Styracosaurus).
In the Carboniferous to Jurassic periods these major earth movements formed the dramatic landscape of Lonsdale and the Aire Gap in Craven District
Five major rock formations from the Devonian and Carboniferous periods are present in Little Pine State Park and Cummings Township.
A general problem with all oxygen related explanations of the giant dragonflies is the circumstance that very large Meganeuridae with a wing span of 45 cm also occurred in the Upper Permian of Lodève in France, when the oxygen content of the atmosphere was already much lower than in the Carboniferous and Lower Permian.
38th parallel structures, a series of carboniferous craters of the United States, approximately lying on the 38th parallel north
They discovered that the “Spirorbis” fossils found in sedimentary strata, including the Joggins and other Carboniferous coal measures, deposited from the Ordovician to Triassic periods are the remains of an extinct order of lophophorates (now called microconchids) unrelated to modern marine tube worms (Annelids) to which the genus Spirorbis belongs.
Sir A. Geikie has shown that the puy type of eruption was common in the British area in Carboniferous and Permian times, as abundantly attested in central Scotland by remains of the old volcanoes, now generally reduced by denudation to the mere neck, or volcanic vent, filled with tuff and agglomerate, or plugged with lava.
Reconnoitered by the New Zealand Antarctic Research Program (NZARP) Allan Hills Expedition, 1964, and named after Marie Stopes, authority on Carboniferous palaeobotany, and hence associated with the geology of the area.
